7 Claims. v

. This invention relates to a. device for smokin tobacco in loose form, and particularly to a device of this character simulating a cigarette or cigar holder, the present application being a continuation in part of my co-pending applications, Ser. No. 577,814, filed February 14, 1945, now Patent 2,546,237, and Ser. No. 618,144, filed September 24, 1945, now abandoned.

The principal objects of the invention are to provide a smoking device of small, compact construction; to provide a smoking device having a substantially cylindrical shaped receptacle and a reciprocable stem forcompacting the tobacco in the receptacle and for pushing the tobacco forwardly therein and to discharge the ashes and accumulated matter subsequent to each use of the device; to provide a smoking device having a tobacco receptacle formed essentially of light weight material composed of spaced apart members interconnected by an insulating covering so as to prevent conduction of heat tothe stem to facilitate handling of thedevice without danger of burning the fingers; and to provide the stem with a chamber for containing a filtering material through which the smoke is drawn.

Further objects of the invention are to provide a cool. smoking device that is sanitary and pleasant to smoke; to provide a smoking device which prevents discharge of tobaccofrom the receptacle when using loose tobacco; to provide a smoking device that is adjustable for containing various amounts of tobacco; to provide a smoking device that is easily disassembled and cleaned; and to provide a smoking device wherein the tobacco may be tamped to enhance-the burning quality thereof.

Referring more in detail to the. drawings;

l designates a smoking device embodying the features of the present invention and which includes a substantially elongated cylindrical -receptacle or chamber 2 and stem 3. The member 2 is preferably of composite construction in that it is composed of a series of substantially ring shaped members 4, 5, 6, l, and 8, which are preferably formed of a light weight material such as, for example, an aluminum alloy. The members 4 to 8 each include substantially cylindrical wall portions 9 having substantially equal inner diameters to form a continuous bore or tobacco receiving space it. The outer end member 8 is of somewhat longer length than the intermediate ring members 5, 6, and I, to provide a cage Dortion II, which may be formed integrally therewith and have a circular series of openings I2 conforming in shape with a plane geometrical figure having greater length than width with the adjacent long sides being sufficiently close to each other to define substantially long narrow bars l3 extendin substantially parallel to the longitudinal axis of the cylindrical end member 8. In the drawings the openings l2 are shown of substantially rectangular shape, with the longer dimensions thereof extending in the direction ofaxis of the receptacle. Intermediate the openings are the relatively narrow bar portions l3 connecting an annular outer rim l4 with the body portion l5 as best shown in Figs. 2 and 3.

The member 4 includes a tapered tube [6 to form an internal tapering seat I! encircling the reduced open end E8 of the member.

In assembling the ring members in concentric axial alignment, and with spaces I 9 therebetween the ring members may be assembled on a mandrel, not shown. The ring members are then Wrapped with a fabric material 20 impregnated with a heat resistant adhesive and which is of sufficient length to lap the outermost ring members 4 and 8. The fabric is also of a length so as to provide one or more laps about the receptacle. After application of the fabric 20, an insulating covering 2|, for example leather, is coated on the innerface 22 thereof, with the adhesive material and wrapped over the fabric with the edges 23 and thereof overlapped and sealed together was to -.form a substantially smooth continuous insulating sheath which retains the rings in spaced assembly and provides a finger hold that is kept in relatively cool condition. After the adhesive is set, the completed receptacle is removed from the mandrel to provide, in effect, a continuous bore. Th ring members are thus retained in spaced relation so as to prevent direct conduction of heat from the cage member to the member 4 having the tapering seat portion with which the stem is engaged as later described. The stem 3 may also be formed of metal and has an elongated tubular portion and a tapering head 26 joins with the tubular portion of the stem by a shoulder 21.

The head 26 has a tapered exterior face 28 corresponding with the tapering seat I! so that it tightly wedges therein and forms a leak tight seal between the stem and the receptacle when the stem is retracted in the receptacle as illustrated in Fig. 3. The stem is preferably formed of relatively thin material, and in the illustrated instance, the head portion 26 is reinforced by a conical insert 29 having its outer end 36 registering with the end to provide a tamping face which cooperates with tobacco that is loaded in the stem to effect compacting the tobacco within the forward end of the receptacle without packing the tobacco too tightly within the stem. The head 26 fits rather tightly within the inner diameter of the ring members 5, ii, 'i, and 8, and therefore it may be desirable to slightly bevel the rear edges of the ring members as indicated 32 to facilitate movement of the head of the stem thereacross. The outer end or the stem has a reduced neck 33 for connecting a bit 34.

In using the smoking device just described the stem is drawn retractively within the receptacle until the head 26 thereon wedges within the tapered seat ii. The smoking device i then filled with tobacco by using the device as a scoop in the tobacco so that the tobacco fills the stem and receptacle. The finger is then placed in the open end of the cage, and the stem is reciprocated within the receptacle to pack the tobacco between the finger and the head 23 of the stem. When the tobacco is suificiently packed the face of the charge is substantially level with the innermost edges of the openings l2 in the cage ll. Upon withdrawal of the stem to wedge the head 26 within the tapered seat ll a space 35 (Fig. 5) is established between the packed tobacco and the tobacco within the stem. The packed tobacco is then lighted and stnficient puffs are made through the stem to establish good burning of the tobacco,

the body of packed tobacco is then shifted into the cage by moving the stern forwardly within the receptacle until the burning face of tobacco is substantially even with the open end of the cage. Smoking can then continue until the tobacco is completely burned. lhe tobacco within the stem serves as a filter to remove nicotine. The long travel of thesmoke through relatively large space 35 and the filter assure a cool smoke. The formation of the receptacle prevents heat of the burning tobacco from being conducted to the stem, consequently the bit and stem remain in, cool condition. After the smoke the ashes may be shaken from the cage of the receptacle by tapping the receptacle on a suitable surface or the burning tobacco may be ejected by the use of the stem. During burning of the packed tobacco the particles become sufficiently united or fused together so that the ashes remain within the cage until the entire mass has been ejected.

The form of the invention shown in Figs, 6 and '7 is substantially the same as the form just described with the exception that the bar portions 36 of the cage 31 are bulged outwardly to allow slight expansion of the packed tobacco therein to assist in retaining the tobacco.

In the form of the invention illustrated in Figs. 8 and 9 the stem 38 and bit 39 are of the same construction as in the first described form of the invention, but the tapered member 40 of the receptacle 4! and cage 42 ar interconnected by a preformed heat resistant sleeve 43 composed of fiber or the like. In this form the members 4| and 42 are pressed into the open ends of the sleeve and if required, may be cemented thereto by a heat resistant adhesive as in the attachment of insulating covering in the first described form of the invention. To facilitate movement of the head of the stem the inner edges of the members 4| and 42 are beveled as indicated at 44 and 45. Otherwise the construction and operation is similar to the other forms of invention.

It is obvious that the smoking device comprises a mouthpiece 34, stem 3 and tobacco receiving chamber 2 wherein'all the parts are in axial alignment and in interconnected relation, and that the tobacco chamber 2 includes the ring 8 which forms an end member of metal of cylindrical form, completely open at both ends, and that it is provided intermediate its ends with a series of parallel substantially rectangular openings l2 so that the adjacent walls of the openings define the long narrow bars l3 and the opposite ends of the openings define the sections of annular Walls of different widths, the wall of greatest width being secured to the insulating wall of the chamber. It is further obvious that the wall of the chamber is formed of insulating material and that the end opposite the metal end member or ring 8 has the member 4 in the form of a tapered metal tube, the larger end of which is secured to the chamber. It is also obvious that the stem 3 has the tapered portion thereof slidably mounted in the tapered metal tube of the chamber to provide a tight fit therein, with the head 26 together with the insert 29 forming a wall thickness to provide a substantial piston surface at the larger end thereof and a bore of suflicient size to receive loose tobacco therein, whereby manipulation of the stem Within the chamber causes tobacco to enter saidstem and provide a filter.

From the foregoing it is obvious that I have provided a smoking device that is of small compact construction and which is constructed for cool smoking of tobacco since the receptacle member is formed to prevent conduction of heat from the burning tobacco to the stem of the device. The relatively large smoke passage and filter also assure cool smoke that is free from oils and most of the nicotine.
